MODE FOR INVENTION

Hereinafter, embodiments in the present disclosure will be described in detail with reference to the accompanying drawings.

The disclosure may, however, be exemplified in many different forms and should not be construed as being limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Exemplary embodiments in the present disclosure are based on a configuration in which a plurality of water treatment sections are provided, and after a portion of inflow water passes through the plurality of water treatment sections sequentially and the remainder of the water passes through only a portion of the plurality of water treatment sections, the water is discharged together externally.

With reference to FIGS. 1 to 4, the water treatment apparatus 100 according to an embodiment in the present disclosure may be configured to include a head 200 and a water treatment unit 300.

With reference to FIGS. 1, 2, and 4, the head 200 according to the exemplary embodiment in the present disclosure may include a head unit 210 and a flow guide portion 220. In addition, with reference to the exemplary embodiment, the head unit 210 may include an inlet portion 211, an outlet portion 212, and a connection portion 213.

With reference to FIGS. 4, 6, and 8, water may flow into the inlet portion 211. To this end, an inlet passage 211 a may be formed in the inlet portion 211. Also, a side of the inlet portion 211 may be connected to a water supply source (not illustrated) by a connector (not illustrated). Accordingly, as illustrated in FIGS. 4, 6, and 8, water from the water supply source may flow into the inlet portion 211 and may pass through the inlet passage 211 a.

According to the exemplary embodiment in the present disclosure as illustrated in FIGS. 1 and 2, a passage closing member C may be provided on the other side of the inlet portion 211 not connected to the connector. Thus, the other side of the inlet portion 211 where water does not flow in may become blocked. On the other hand, a connector connected to the water supply source may also be connected to both one side and the other side of the inlet portion 211 so that water may flow into both the one side and the other side of the inlet portion 211.

The outlet portion 212 may allow water to be discharged externally therethrough as illustrated in FIGS. 4, 6, and 8. To this end, an outflow passage 212 a may be formed on the outlet portion 212. Also, one side of the outlet portion 212 may be connected to, for example, a water discharge member (not illustrated) or other water treatment apparatuses (not illustrated) by a connector. Thus, with reference to FIGS. 4, 6, and 8, water treated by the water treatment unit 300 may flow into the outlet portion 212. Further, the treated water may pass through the outflow passage 212 a of the outlet portion 212 and be discharged externally through the water discharge member or flow into another water treatment apparatus.

With reference to the exemplary embodiment as illustrated in FIGS. 1 and 2, a passage closing member C may also be provided on the other side of the outlet portion 212 to which the connector is not connected. Thus, the other side of the outflow passage 212 a through which water is not discharged may become blocked. However, water may be discharged from both sides of the outlet portion 212.

The connection portion 213 may be connected to the inlet portion 211 and the outlet portion 212. The connection portion 213 may also be connected to the integrated inlet portion 211 and outlet portion 212, but is not limited thereto. For example, any widely used configuration in which the connection portion 213 is connected to the inlet portion 211 and the outlet portion 212 may be used.

The water treatment unit 300 may be connected to the connection portion 213 as illustrated in FIGS. 1 and 4. To this end, a connecting space of the water treatment unit 300 may be formed in the connection portion 213 as illustrated in the exemplary embodiment of FIG. 4. In such a space of the connection portion 213, a connecting passage 211 b connected to the inlet passage 211 a of the inlet portion 211 and a connecting passage 212 b connected to the outflow passage 212 a of the outlet portion 212 as described above may be connected.

Thus, as illustrated in FIGS. 4, 6, and 8, water having passed through the inlet passage 211 a passes through the connecting passage 211 b to the water treatment unit 300, and water treated by the water treatment unit 300 may pass through the connecting passage 212 b to flow to the outflow passage 212 a.

As illustrated in FIGS. 4, 6, and 8, the flow guide portion 220 may guide the inflow water to flow from the inlet portion 211 to the water treatment unit 300 and guide the water treated by the water treatment unit 300 to flow to the outlet portion 212. To this end, with reference to the exemplary embodiment illustrated in FIGS. 2 and 4, the flow guide portion 220 may include a passage forming member 221 and an opening/closing member 222.

Upper and lower portions of the passage forming member 221 may be open as in the exemplary embodiment illustrated in FIG. 4. In addition, an inflow portion 311, which will be described below, included in the water treatment unit 300 may be connected to the open lower portion of the passage forming member 221. Also, an inflow passage 221 a connected to the inlet portion 211 may be formed in the passage forming member 221 with reference to the illustrated exemplary embodiment. According to the exemplary embodiment in the present disclosure, the inflow passage 221 a may be connected to the connecting passage 211 b connected to the inlet passage 211 a of the inlet portion 211 through an inflow connecting aperture 221 c.

Thus, water having passed through the inlet passage 211 a as illustrated in FIG. 4 may flow into the inflow passage 221 a through the inflow connecting aperture 221 c. Also, water may flow into the inflow portion 311 of the water treatment unit 300 through the inflow passage 221 a.

In addition, with reference to the illustrated exemplary embodiment in FIG. 4, the passage forming member 221 may have an outflow passage 221 b formed therein and connected to the outlet portion 212 together with the connection portion 213. Also, the outflow passage 221 b may be connected to the connecting passage 212 b connected to an outflow passage 212 a of the outlet portion 212 through an outflow connecting aperture 221 d formed in the passage forming member 221.

Thus, as illustrated in FIG. 4, water discharged from an outflow portion 312, included in the water treatment unit 300 may flow into the outflow passage 212 a of the outlet portion 212 through the outflow connecting aperture 221 d and the connecting passage 212 b after passing through the outflow passage 221 b.

With reference to the exemplary embodiment as illustrated in FIG. 4, the opening/closing member 222 may be rotatably provided in the passage forming member 221. In addition, with reference to the exemplary embodiment as illustrated in FIG. 5, a plurality of opening/

closing apertures

222 a and 222 b may be formed in the opening/closing member 222. Also, as illustrated in FIGS. 5, 7, and 9, a plurality of first inflow apertures 311 a formed in the inflow portion 311 or a plurality of second inflow apertures 311 b may be opened and closed according to the rotating location. With reference to the exemplary embodiment, the opening/closing member 222 may include two opening/

closing apertures

222 a and 222 b, in detail, a first opening/closing aperture 222 a and a second opening/closing aperture 222 b.

The plurality of first inflow apertures 311 a and the plurality of second inflow apertures 311 b may be spaced apart from each other by a predetermined interval with reference to the exemplary embodiment as illustrated in FIGS. 5, 7, and 9. For example, with reference to the illustrated exemplary embodiment, the plurality of first inflow apertures 311 a and the plurality of second inflow apertures 311 b may form groups of apertures. Also, with reference to the illustrated exemplary embodiment, the plurality of first inflow apertures 311 a and the plurality of second inflow apertures 311 b may be formed in the circumference of a virtual circle on the inflow portion 311, and diameters thereof may be reduced in a single direction.

In addition, with reference to the exemplary embodiment as illustrated in FIGS. 5, 7, and 9, the plurality of opening/

closing apertures

222 a and 222 b, for example, the first opening/closing aperture 222 a and the second opening/closing aperture 222 b in the illustrated exemplary embodiment, may have slots with different lengths. Also, with reference to the exemplary embodiment, the apertures may be spaced apart from each other by a predetermined interval. Further, with reference to the exemplary embodiment, the first opening/closing aperture 222 a and the second opening/closing aperture 222 b may be formed in the opening/closing member 222 in locations corresponding to locations of the plurality of first inflow apertures 311 a and the plurality of second inflow apertures 311 b formed in the inflow portion 311 of an inlet/outlet member 310 included in the water treatment unit 300 to be described below. For example, the first opening/closing aperture 222 a and the second opening/closing aperture 222 b may also be formed in the circumference of a virtual circle on the inflow portion 311.

Thus, on a rotating location of the opening/closing member 222 as illustrated in FIG. 5, only the first opening/closing aperture 222 a of the opening/closing member 222 may communicate with the plurality of first inflow apertures 311 a of the inflow portion 311 as illustrated in FIGS. 4 and 5. Thus, as illustrated, all of the water flowing into the inflow passage 221 a of the passage forming member 221 may flow into only the plurality of first inflow apertures 311 a through the first opening/closing aperture 222 a.

Also, after the water flowing into the plurality of first inflow apertures 311 a passes through to the lower portion of the water treatment unit 300 as illustrated in FIG. 4, the water may be treated by passing through the first water treatment section 321 and the second water treatment section 322 sequentially, and then, may be discharged through the outflow portion 312 to flow into the head 200.

Further, on a rotating location of the opening/closing member 222 as illustrated in FIG. 7, the first opening/closing aperture 222 a of the opening/closing member 222 may communicate with a portion of the plurality of first inflow apertures 311 a of the inflow portion 311 as illustrated in FIGS. 6 and 7, and the second opening/closing aperture 222 b may communicate with a portion of the plurality of second inflow apertures 311 b of the inflow portion 311. Accordingly, as illustrated, a portion of the water flowing into the inflow passage 221 a of the passage forming member 221 may flow into a portion of the plurality of first inflow apertures 311 a through the first opening/closing aperture 222 a, and the remainder of the water may flow into a portion of the plurality of second inflow apertures 311 b through the second opening/closing aperture 222 b.

In addition, after the water flowing into a portion of the plurality of first inflow apertures 311 a may flow into a lower portion of the water treatment unit 300 as illustrated in FIG. 6, the water is treated by passing through the first water treatment section 321 and the second water treatment section 322 included in the water treatment unit 300 sequentially, and may be discharged through the outflow portion 312. Also, water flowing into a portion of the plurality of second inflow apertures 311 b as illustrated in FIG. 6, is treated by passing through only the second water treatment section 322 included in the water treatment unit 300, and may be discharged through the outflow portion 312.

Also, on a rotating location of the opening/closing member 222 as illustrated in FIG. 9, the first opening/closing aperture 222 a of the opening/closing member 222 may communicate with a portion of the plurality of second inflow apertures 311 b as illustrated in FIGS. 8 and 9, and the second opening/closing aperture 222 b may communicate with a portion of the plurality of first inflow apertures 311 a of the inflow portion 311. Thus, as illustrated, a portion of the water flowing into the inflow passage 221 a of the passage forming member 221 may flow into a portion of the plurality of second inflow apertures 311 b through the first opening/closing aperture 222 a, and the remainder of the water may flow into a portion of the plurality of first inflow apertures 311 a through the second opening/closing aperture 222 a.

Further, water flowing into a portion of the plurality of first inflow apertures 311 a may flow into the lower portion of the water treatment unit 300 as illustrated in FIG. 8, and then the water may be treated by passing through the first water treatment section 321 and the second water treatment section 322 included in the water treatment unit 300 sequentially, and may be discharged through the outflow portion 312. Also, water flowing into a portion of the plurality of second inflow apertures 311 b as illustrated in FIG. 8, may be treated by passing through only the second water treatment section 322 included in the water treatment unit 300, and may be discharged through the outflow portion 312.

Thus, the water flowing into the inflow passage 221 a of the passage forming member 221 may flow into the first inflow aperture 311 a or the second inflow aperture 311 b of the inflow portion 311 in the water treatment unit 300 by the rotation of the opening/closing member 222, and the flow rate of the water passing through the first inflow aperture 311 a or the second inflow aperture 311 b may also be adjusted. Therefore, the flow rate of the water treated by passing through a portion of the plurality of

water treatment sections

321 and 322, to be described below, of the water treatment unit 300, for example, through the water treatment section 321, may be adjusted.

Accordingly, adequate amounts of functional substances included in the water treatment section 321 may be dissolved in the inflow water, or an adequate amount of positive or negative ions may be relatively increased.

The flow guide portion 220 may further include a connection member 223 and a gripping member 224 with reference to the exemplary embodiment as illustrated in FIGS. 2 and 4. With reference to the exemplary embodiment, the connection portion 223 may be connected to the opening/closing member 222 to block the open upper portion of the passage forming member 221. Also, the gripping member 224 may be connected to the connection member 223. Thus, a user may easily rotate the opening/closing member 222 described above by using the gripping member 224, and thereby, a user may easily adjust the flow rate of the water treated by sequentially passing through both the first and second

water treatment sections

321 and 322 of the water treatment unit 300 and the flow rate of the water treated by passing through only the second water treatment section 322.

Further, with reference to the exemplary embodiment in FIG. 2, an elastic member 225 may be provided between the opening/closing member 222 and the connection member 223. Thus, since the elastic force of the elastic member 225 is exerted on the opening/closing member 222 and the connection member 223, connectivity between the opening/closing member 222 and the connection member 223 may be improved. The elastic member 225 may be a coil spring with reference to the exemplary embodiment. However, the elastic member 225 is not limited to being a coil spring, and any elastic member 225 that is commonly used and provides equivalent elasticity may be used.

Additionally, with reference to the exemplary embodiment in FIGS. 2 and 4, an auxiliary connection member 214 may be connected to the connection member 213. The connection of the water treatment unit 300 to the connection member 213 may be supported by such auxiliary connection member 214. Also, a locking release member 215 may be provided in the auxiliary connection member 214 with reference to the exemplary embodiment. The connection of the water treatment unit 300 to the connection portion 213 may be locked or unlocked by the locking release member 215.

To this end, a locking release portion 215 a may be provided in locking release member 215 with reference to the exemplary embodiment in FIGS. 2 and 4. Also, when the locking release member 215 is rotated while the water treatment unit 300 being connected to the connection member 213 and the auxiliary connection member 214, the connection of the water treatment unit 300 to the connection member 213 and the auxiliary connection member 214 may be locked or unlocked. Thus, the water treatment unit 300 may be easily connected to or separated from the connection portion 213 and the auxiliary connection member 214.

In addition, a bracket 216 may be connected to the auxiliary connection member 214 with reference to the exemplary embodiment in FIGS. 2 and 4. Thus, a water treatment apparatus 100 according to an exemplary embodiment in the present disclosure may easily be disposed on another apparatus or on a wall or other internal structure.

With reference to the exemplary embodiment in FIGS. 1 and 4, the water treatment unit 300 may be connected to the connection portion 213 of the head unit 210 included in the head 200. Also, with reference to the exemplary embodiment, the water treatment unit 300 may be include a plurality of

water treatment sections

321 and 322. Further, as illustrated in FIGS. 4, 6, and 8, a portion of the water flowing into the inlet portion 211 of the head unit 210 provided in connection with the head 200 may pass through the plurality of

water treatment sections

321 and 322 sequentially, the remainder of the water may pass through only a portion of the plurality of

water treatment sections

321 and 322, and the water together may flow into the outlet portion 212.

To this end, the water treatment unit 300 may include an inlet/outlet member 310 and a housing 320 with reference to the exemplary embodiment in FIGS. 3 and 4.

Also, with reference to the exemplary embodiment in FIGS. 3 and 4, the inlet/outlet member 310 may include an inflow portion 311 and an outflow portion 312.

Water may flow into the inflow portion 311 from the head 200 with reference to FIGS. 4, 6 and 8. To this end, a plurality of first inflow apertures 311 a and a plurality of second inflow apertures 311 b may be formed in the inflow portion 311 as previously described and with reference to the exemplary embodiment in FIGS. 4 through 9. Thus, as illustrated in FIGS. 4, 6, and 8, a portion of the water flowing from the head 200 may flow into the water treatment unit 300 through the plurality of first inflow apertures 311 a. Also, the remainder of the water may flow into the water treatment unit 300 through the plurality of second inflow apertures 311 b.

With reference to FIGS. 4, 6 and 8, water may be discharged to the head 200 through the outflow portion 312. To this end, with reference to the exemplary embodiment in FIGS. 4 through 9, a plurality of outflow apertures 312 a may be formed in the outflow portion 312. Thus, as illustrated in FIGS. 4, 6, and 8, water treated by the water treatment unit 300 may be discharged to the head 200 through a plurality of outflow apertures 312 a.

The housing 320 may be connected to the inlet/outlet member 310 with reference to the exemplary embodiment in FIGS. 4, 6, and 8. For example, the housing 320 may be fitted to be connected to the inlet/outlet member 310 with reference to the exemplary embodiment. However, the connection of the housing 320 to the inlet/outlet member 310 is not only limited to the description above, but may also be connected by an adhesive, a bolt, a screw, or the lie, and any other common configurations used for the connection to the inlet/outlet member 310 may be applied thereto.

In addition, with reference to the exemplary embodiment in FIGS. 3, 4, 6, and 8, the housing 320 may include a first water treatment section 321 and a second water treatment section 322.

With reference to the exemplary embodiment, the first water treatment section 321 and the second water treatment section 322 may be partitioned thereby. Also, the partitioning member 327 may be composed of a material in which water may pass through.

Thus, as illustrated in FIGS. 4, 6, and 8, water may pass through the first and second

water treatment portions

321 and 322 without mixing of substances included in the first and second

water treatment portions

321 and 322. The partitioning member 327 may be composed of, for example, a non-woven fabric. However, the material composing the partitioning member 327 is not limited to the described material, but may be of any other material in which water may pass through and which may allow for partitioning into the first and second

water treatment sections

321 and 322.

With reference to the exemplary embodiment in FIGS. 3, 4, 6, and 8, a through-hole 327 a may be formed in the partitioning member 327. The through-hole 327 a of the partitioning member 327 with reference to the illustrated exemplary embodiment may be penetrated by the inflow portion 311 of the inlet/outlet member 310 or a third guide member 325 or a fourth guide member 326 which will be described below. Thus, water flowing from the plurality of first inflow apertures 311 a formed in the inflow portion 311 of the inlet/outlet member 310 may flow into the lower portion of the housing 320 through a first passage 323 a of a first guide member 323, a second passage 324 a of a second guide member 324, and a third passage 326 a of the fourth guide member 326 as described below.

The first water treatment section 321 may include functional substances such as phosphate to remove pipeline scale. Thus, functional substances such a phosphate may be dissolved in the water having passed through the first water treatment section 321. Also, the first water treatment section 321 may include an ion-exchange resin. Thus, a relatively high amount of positive or negative ions may be included in the water having passed through the first water treatment section 321 according to the type of ion-exchange resin. Further, the second water treatment section 322 may include carbon particles. Thus, water having passed through the second water treatment section 322 may be treated by carbon particles absorbing and removing various impurities including microorganisms from the water.

In addition, as illustrated in FIGS. 4, 6, and 8, a portion of the water flowing into the inflow portion 311, for example, water having passed through a plurality of first inflow apertures 311 a of the inflow portion 311, may be treated by passing through the first and second

water treatment sections

321 and 322 sequentially. Also, the remainder of the water, for example, water having passed through the plurality of second inflow apertures 311 b of the inflow portion 311 as illustrated, may be treated by passing through only the second water treatment section 322, and then, the water together may be discharged through the outflow portion 312.

Accordingly, as described above, when the first water treatment section 321 includes functional substances or an ion-exchange resin and the second water treatment section 322 includes carbon particles, a portion of the water having passed through the plurality of first inflow apertures 311 a of the inflow portion 311 may pass through the first water treatment section 321 and may be in a state in which functional substances are dissolved or a relatively high amount of positive or negative ions are contained therein, and further, may pass through the second water treatment section 322 sequentially, so that microorganisms as well as various impurities may be removed. Also, water having passed through the plurality of second inflow apertures 311 b of the inflow portion 311 may pass through only the second water treatment section 322 to remove various impurities, including microorganisms. Further, water treated by passing through both the first and second

water treatment sections

321 and 322 or water treated by passing through only the second treatment portion 322 in such ways, may be discharged together to the head 200 through the outflow aperture 312 a of the outflow portion 312.

Thus, as described above, amounts of functional substances dissolved in water and the amount of positive or negative ions included in water may be adjusted by adjusting the flow rate of the water passing through the plurality of first inflow apertures 311 a and the plurality of second inflow apertures 311 b of the inflow portion 311, to thus remove various impurities, including microorganisms.

Also, the second water treatment section 322 may be located above the first water treatment section 321 with reference to the exemplary embodiment illustrated in FIGS. 3, 4, 6, and 8. Further, as illustrated in FIGS. 4, 6, and 8, a portion of the water flowing from the inflow portion 311, for example, water passing through the plurality of first inflow apertures 311 a of the inflow portion 311, may flow to the lower portion of the housing 320, and then, may pass through the first and second

water treatment sections

321 and 322 sequentially. In addition, as illustrated, the remainder of the water, for example, water having passed through the plurality of second inflow apertures 311 b of the inflow portion 311, may only pass through the second water treatment section 322.

To this end, with reference to the exemplary embodiment illustrated in FIGS. 3, 4, 6, and 8, the housing 320 may further include a first guide member 323, a second guide member 324, and a third guide member 325.

With reference to the exemplary embodiment illustrated in FIGS. 3, 4, 6, and 8, a first passage 323 a may be formed in the first guide member 323. The first guide member 323 may be connected to the inflow portion 311 of the inlet/outlet member 310 with reference to the exemplary embodiment illustrated in FIGS. 4, 6, and 8, and the first passage 323 a of the first guide member 323 may thereby be connected to the plurality of first inflow apertures 311 a. Accordingly, as illustrated, water having passed through the plurality of first inflow apertures 311 a of the inflow portion 311 may flow into the first passage 323 a of the first guide member 323.

With reference to the exemplary embodiment illustrated in FIGS. 3, 4, 6, and 8, a second passage 324 a may be formed in the second guide member 324. Also, the first guide member 323 may be connected to the second guide member 324, and thereby, the second passage 324 a of the second guide member 324 may be connected to the first passage 323 a of the first guide member 323. Accordingly, as illustrated, water having passed through the first passage 323 a of the first guide member 323 may flow into the second passage 324 a of the second guide member 324 and may thus flow into a lower portion of the housing 200.

The second guide member 324 may be inserted into the third guide member 325 with reference to the illustrated exemplary embodiment in FIGS. 4, 6, and 8. Accordingly, a bypass passage 325 a connected to the plurality of second inflow apertures 311 b and the second water treatment section 322 may be formed between the third guide member 325 and the second guide member 324. With reference to the illustrated exemplary embodiment, the bypass passage 325 a may be connected to the second water treatment section 322 by a bypass aperture 325 b formed in the third guide member 325. Accordingly, water having passed through the plurality of second inflow apertures 311 b may flow into the second water treatment section 322.

In addition, with reference to the illustrated exemplary embodiment, a filtering member 325 c in which a plurality of apertures are formed may be provided in the bypass aperture 325 b of the third guide member 325. Thus, as described above, in a case in which carbon particles are included in the second water treatment section 322, carbon particles of the second water treatment section 322 may be prevented from flowing into the bypass passage 325 a through the bypass aperture 325 b.

Also, with reference to the exemplary embodiment illustrated in FIGS. 3, 4, 6, and 8, the housing 320 may further include a fourth guide member 326. With reference to the illustrated exemplary embodiment, the third passage 326 a may be formed in the fourth guide member 326. Further, the fourth guide member 326 may be connected to the third guide member 325, and thereby, the second passage 324 a of the second guide member 324 may be connected to the third passage 326 a of the fourth guide member 326. Accordingly, as illustrated, water having passed through the second passage 324 a of the second guide member 324 may flow into the third passage 326 a of the fourth guide member 326 to flow in the third passage 326 a, and may flow into the lower portion of the housing 320.

Further, water flowing to the lower portion of the housing 320 in such a way may flow into the upper portion of the housing 320 as illustrated in FIGS. 4, 6, and 8, and may flow into the head 200 through the outflow aperture 312 a formed in the outflow portion 312 of the inlet/outlet member 310, after being treated by passing through the first water treatment section 321 and the second water treatment section 322 sequentially.

Additionally, the non-described reference numeral “0” indicates sealing members such as an o-ring.

As set forth above, when using the water treatment apparatus according to an exemplary embodiment in the present disclosure, a plurality of water treatment sections which treat inflow water may be included; a portion of the water is treated by passing through a plurality of water treatment sections sequentially, the remainder of the water is treated by passing through only a portion of the plurality of water treatment sections, and the water together may be discharged externally; the flow rate of water passing through a portion of the water treatment sections may be adjusted, adequate amounts of functional substances may be dissolved, or an adequate amount of positive or negative ions may be relatively increased in the inflow water.

While exemplary embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the scope of the invention as defined by the appended claims.
